“Today” show co-host Matt Lauer has been fired due to inappropriate sexual behavior in the workplace, NBC announced Wednesday morning.

Lauer's co-anchor Savannah Guthrie was joined by Hoda Kotb to address his termination on Wednesday's show.

"We just learned this moments ago, just this morning," Guthrie said. "As I'm sure you can imagine, we are devastated. We are still processing all of this."

NBC News Chairman Andrew Lack said in a memo to employees that a complaint, which was made by a colleague of Lauer's, prompted a serious review and represented a "clear violation of our company's standards."

"Our highest priority is to create a workplace environment where everyone feels safe and protected, and to ensure that any actions that run counter to our core values are met with consequences, no matter who the offender," Lack said.

Social media quickly lit up with reaction, including from President Trump:

Wow, Matt Lauer was just fired from NBC for “inappropriate sexual behavior in the workplace.” But when will the top executives at NBC & Comcast be fired for putting out so much Fake News. Check out Andy Lack’s past!

When a news organization fires a hugely prominent figure, it should have case ready to present to public. Don't throw two anchors on air who don't know what's going on. When CBS fired Rose, public knew overwhelming evidence. With NBC and Lauer, public in dark.

Broadcasting live from the Conservative Political Action Conference in Oxon Hill, Md. Wednesday, Sean Hannity blasted the media for continuing to criticize President Trump while ignoring his accomplishments.
